Stranded Gel-free Loose Tube APLArmored Cable (GYFA(ALL DRY)) Fiber Optic Cable

The fibers, are positioned in a loose tube made of a high modulus plastic. The interstice inside and outside of the tubes are filled with water-blocking yarns and water-blocking tape. A fiber reinforced plastic rod(FRP), coated with polyethylene if necessary locates in the center of core as a strength member. Tubers (and fillers) are stranded around the strength member to form a compact and circular cable core. A layer polyethylene sheath is extruded around the cable core to form a cable.
